vector corrosion services - Projects
Vector Corrosion Services (VCS) has successfully provided solutions for asset managers facing corrosion and concrete durability concerns. Here are projects that we have completed that include investigation, corrosion engineering, and cathodic protection design services for infrastructure and building assets.
Ohio DOT Galvanic Anode Installation QA/QC
Project Name: Ohio Galvanic Anode Quality Control and Assurance
Structure: Various Bridge Structures in Ohio
Location: Ohio DOT - District 7
Client: Ohio Department of Transportation
Technologies: Structural Health Monitoring
Project Issues: Rehabilitation of Bridge Abutments with Galvanic Anodes
Project Date: Summer 2014
Vector Corrosion Services (VCS) performed installation quality control, supplied and installed monitoring stations, and performed data analysis for galvanic cathodic protection systems installed on 10 bridges in Ohio DOT’s District 7.
The Ohio Department of Transportation (ODOT), like many states, performs substructure rehabilitation on various structures throughout the state. As part of their maintenance strategy, ODOT includes galvanic cathodic protection of bridge abutments as a cost-effective means to extend the life of existing structures. As per ODOT requirements, a NACE Certified Cathodic Protection Specialist was required to train the contractors in installation of the GCP systems and to install and the anode monitoring stations.
VCS provided a NACE Certified Cathodic Specialist (CP-4) to conduct on-site installation QC and installation of the monitoring stations. VCS instructed the various contractors and DOT personnel on proper installation of the galvanic anodes and installed manual monitoring stations on each abutment. VCS also installed instrumentation monitoring stations on select structures so that the performance of the CP systems could be tracked with time. Monitoring of the systems is intended to provide ODOT with an accurate determination of the anode’s service life, verify the effectiveness of the system, inform ODOT design procedures, and verify proper performance.
